SIN
The SIN function calculates the sine of an angle expression. The result returned by SIN is a decimal value with the same dimensions as the specified expression.
Return Value
DECIMAL
Syntax
SIN(angleexpression)
Arguments
 angleexpression

A numeric expression that contains an angle value, which is specified in radians.
Examples
Example 896 Calculating the Sine of an Angle in Radians
This example calculates the sine of an angle of 1 radian. The statements
DECIMALS = 5
SHOW SIN(1)
produce the following result.
0.84147
Example 897 Calculating the Sine of an Angle in Degrees
This example calculates the sine of an angle of 30 degrees. Since 1
degree = 2*(pi)/360
radians, 30
degrees is about 30*2*3.14159/360
radians. The OLAP DML statement
SHOW SIN(30 * 2 * 3.14159 / 360)
produces the following result.
0.50000
